[QUOTE="rogerh, post: 107674, member: 6278"] Sorry for my lack of feedback until now, I had some extra time today so did a little trouble-shooting. I checked the fuel pickup tube screen and it was clean and looked almost new so don't think fuel is being restricted from there. I loosened 3 of the injector lines(one at a time) to see if I could isolate an injector and could tell the engine ran even rougher when they were loosened, so don't think its one of those injectors. Didn't do the last injector line because it was harder to get to. Also, loosening the injectors made the resulting engine miss very obvious and even more severe than the problem I'm noticing ... so not even sure its worth trying the 4th one. Because I had the machine inside a barn I was able to see better the smoke that is being generated when it starts missing ... its black with some white ... not sure what that means. The engine still cranks effortlessly (in less than 3 seconds after 15 seconds of glow plug) and it runs fine with good power until about 1/2 throttle then starts running rough and blowing smoke and lacks power [/QUOTE]
